A method for determining a charging profile from a large number of charging profiles for a current charging process for charging an electrical energy store includes determining a current state of the energy store, determining the charging profile from the large number of charging profiles based on the current state of the energy store, and charging the energy store based on the determined charging profile.

System and method for determining charging profiles

An electrified motor vehicle includes a display unit for displaying at least one residual range, a high-voltage accumulator, and at least one electronic control unit which determines an expected minimum range on the basis of the state of charge of the high-voltage accumulator and which determines, on the basis of the temperature of the high-voltage accumulator and the state of charge of the high-voltage accumulator, a temperature-dependent bonus range which is displayed instead of the minimum range if the minimum range has dropped to zero.

An electric traction machine, a motor vehicle, and a method for controlling dissipated heat in the electrical power plant of the motor vehicle are described herein. The power plant is supplied with a current, where, in order to provide a predetermined amount of dissipated heat, a ratio between a field-forming and a torque-forming current deviating from an optimum ratio for a respective operating point of the power plant is prescribed. The predetermined dissipated heat is provided by a power plant embodied as a magnet-less three-phase alternator while a rotor current flowing through a rotor of the three-phase alternator is adjusted, the field-forming and the torque-forming currents being prescribed such that acoustic interference signals of the three-phase alternator are minimized by the ratio, and the rotor current is adjusted such that the predetermined dissipated heat is provided by a combination of the rotor current and the ratio minimizing the interference signals.

A method operates a storage system for a vehicle. The storage system has a first storage module and a second storage module for providing electrical energy to or for receiving electrical energy from a distribution network. The distribution network is coupled to an electrical motor of the vehicle. The first storage module is coupled by a direct current voltage converter to the distribution network. The method determines whether an amount of a voltage difference between a power supply voltage of the distributor network and a first storage voltage of the first storage module is equal to or less than a voltage threshold value. The method carries out one or more measures for increasing the amount of the voltage difference when it is determined that the amount is equal to or less than the voltage threshold value.

Multiple storage system and method for operating a multiple storage system

A method and a system are provided for controlling waste heat generated by a motor vehicle having an electric drive including a rechargeable battery and an electric machine for driving the motor vehicle. The method includes determining the thermal load on at least two components of the electric drive; if a first electric component of the electric drive has a lower thermal load than a second electric component, actuating the electric drive such that the generation of waste heat in the first electric component increases and the generation of waste heat in the second electric component does not increase; and if the second electric component has a lower thermal load than the first electric component, actuating the electric drive such that the generation of waste heat in the second electric component increases and the generation of waste heat in the first electric component does not increase.
